An error occurs when the encoder is reading data from or writing data to EEPROM.
Check if the motor is properly grounded. Make sure the ground end (green) of
1.
the power cable (green end) is grounded to the servo drive heat sink.
Check if the connection for the encoder signal cable is normal. Make sure the
2.
encoder signal cable is separated from the power supply or any high-current
cables to avoid interference.
Use shielded cable for the encoder cable. Pull out the wire mesh and have it

correctly grounded.
Check the motor speed and make sure it is within the rated range.
4.
If the issue persists, send your servo motor back to the distributor or contact Delta.
Cycle power on the servo drive.
